The Faculty, Casey/Zeke picspam.
This is my new (old) obsession. The Faculty is a scifi movie that was released in 1998, directed by Robert Rodriguez and starring Elijah Wood (Casey) and Josh Hartnett (Zeke). Aliens are taking over their high school! I liked it a lot back then (admittedly mostly because Josh Hartnett did strange things to my teenage heart) and few weeks ago I randomly started reading fanfiction for it and then I had to rewatch the movie.
Zeke is the bad boy and Casey is the nerd. Opposites attract and all that. Together, they fight aliens!
